[Physltest] [Phys-L] Re: flipping over upon reflection



Does anyone have a qualitative argument for this behavior, without the
equations: slower wave speed in the second medium (larger k, smaller
wavelength) causes the reflected wave to be flipped over?

A boundary with a MORE massive string beyond is KIND of like a rigid
attachment of the end. A boundary with a LESS massive string beyond
is KIND of like a free end. This explanation requires one to know
what happens at fixed and free ends, but I don't think it takes much
intuition to appreciate those results.
